NN300 vs NN700: Auto Quad Angle Underpinner vs Touchscreen Plate-Clamping CNC Underpinner
Side-by-side comparison
| Dimension | NN300 | NN700 |
|---|---|---|
| Use case | High-end galleries and premium frame shops demanding zero-gap miter joints | High-volume factories upgrading cut-and-join with low-supervision quad-angle joining |
| Throughput | 1,000–3,000 frames/day | ~15 frames/min |
| Automation | Touchscreen CNC with coordinated plate clamping | Fully automatic (PLC) |
| Ideal daily volume | 1,000–3,000 frames/day | 2,000–8,000 frames/day (configuration-dependent) |
| Primary scenario | factory | studio |
| CE certification | Yes | Yes |
| Factory-direct OEM | XKY Frame | XKY Frame |

Decision tree
Is factory or studio your primary scale?
Lean NN300 for factory; lean NN700 for studio.
Do you need maximum throughput on stable SKUs?
Compare throughput rows — typically the NN300 class for line layouts.

FAQ
What is the main difference between NN300 and NN700?
The NN300 is a line-grade quad-angle underpinner for cut-and-join layouts: all four corners are nailed at once, with auto push-off to the outfeed conveyor—roughly 300% higher throughput than manual pneumatic underpinners.
Can I run NN300 and NN700 on the same line?
Some factories use different stations for different profile classes. Share your layout sketch on /contact/quote for engineering review.
Are both models CE certified?
Yes. XKY Frame supplies CE-certified machinery with documentation for export clearance.
Who is the flagship PRO model for?
It combines touchscreen control with dual-drive plate clamping for customers who accept no compromise on right-angle alignment—top-tier gap-free galleries and large enterprises.
